Plasma antenna transmits and receives radio waves, researchers report

Scope: the news item, dated 7 October 2026, reports that researchers presented a plasma-based antenna, described in the text as the fourth state of matter. Stated finding: the antenna transmits and receives radio waves to establish wireless connections. The researchers compare the device to a lightsaber. The text gives no technical parameters, frequencies, range, efficiency or validation stage, and it contains no cybersecurity details or protection recommendations. The source therefore records progress in communication hardware without indicating immediate practical application. Relevance: readers following wireless communications can note a research line on plasma-based antennas, but the text does not allow performance assessment. Verification: consult the original publication and any scientific paper it cites, then check authors, date and institution before quoting. Rota Nacional does not evaluate or reproduce this hardware. If you use AI to study the material, paste only the public passage, never customer personal data or credentials, and confirm figures against the original.
